Subject: [GIT PULL] x86 fixes
Date: Fri, 5 Jun 2015 10:40:04 +0200	[thread overview]
Message-ID: <20150605084004.GA3915@gmail.com> (raw)

Linus,

   # HEAD: 425be5679fd292a3c36cb1fe423086708a99f11a x86/asm/irq: Stop relying on magic JMP behavior for early_idt_handlers

Misc fixes:

  - early_idt_handlers[] fix that fixes the build with bleeding edge tooling

  - build warning fix on GCC 5.1

  - vm86 fix plus self-test to make it harder to break it again

  out-of-topic modifications in x86-urgent-for-linus:
